The Corolla uses a CVT (Continuously Variable Transmission). The functions of the transmission are: 1. Changing the transmission ratio; 2. Expanding the torque and speed of the drive wheels; 3. Allowing the car to reverse; 4. Facilitating gear shifting or power output. Taking the 2021 Corolla as an example, its body dimensions are: length 4635mm, width 1780mm, height 1455mm, wheelbase 2700mm, fuel tank capacity 43L, and curb weight 1410kg. The 2021 Corolla features a MacPherson strut front suspension and an E-type multi-link rear suspension. It is equipped with a 1.8L naturally aspirated engine, producing a maximum horsepower of 98PS, a maximum power of 72kW, and a maximum torque of 142Nm, paired with an electronic continuously variable transmission.

As a long-time Corolla owner who has driven several models, I remember most newer Corollas use continuously variable transmissions, which Toyota calls CVT. This thing drives incredibly smoothly with no jerking sensations, and it's super fuel-efficient for city commuting. My 2019 Corolla has a CVT, and it averages around 6L/100km in daily driving - much more economical than traditional automatic transmissions. Maintenance is simple too, just regular transmission fluid changes costing a few hundred bucks each time. The downside is the engine gets a bit noisy during hard acceleration, especially when climbing hills at high speed, but you get used to it. Toyota's tuning is excellent, with high reliability - I've never heard of major issues. Of course, older Corolla models had manual transmission options, but CVT is now the dealership's main offering. It's genuinely economical and practical, suitable for all road conditions.

From a professional perspective, the Corolla primarily uses a CVT (Continuously Variable Transmission) system, which dominates especially in newer models. It achieves seamless gear shifting through a steel belt and pulley mechanism, keeping the engine within its optimal efficiency range and significantly improving fuel economy. Compared to traditional automatic transmissions (AT), CVT offers smoother acceleration with reduced jerking, achieving urban fuel consumption as low as 7L/100km. However, it may produce more noise under high-speed, high-power demands, which Toyota has mitigated through electronic control optimization. Manual transmission versions remain available in base trims or specific markets but are increasingly rare. Maintenance-wise, CVT only requires periodic fluid changes, making it simpler and more durable than DCT (Dual-Clutch Transmission). Toyota's design ensures long-term reliability with modest repair costs, easily surpassing 100,000 km under normal usage. This choice reflects Toyota's fuel-efficiency-first philosophy.

As a first-time young Corolla owner, it took me some time to understand the transmission. Currently, the mainstream Corolla comes with a CVT (Continuously Variable Transmission), which provides smooth acceleration without gear shifts and is fuel-efficient. My new car has low daily commuting fuel consumption and is user-friendly with its simple operation. Occasionally, during sudden acceleration, the engine makes a humming sound, but my friend says it's normal by design. Toyota also offers a manual transmission option for the base model, though it's less common. Maintenance is straightforward and affordable.
